WebThe bisection method uses the intermediate value theorem iteratively to find roots. Let f ( x) be a continuous function, and a and b be real scalar values such that a < b. Assume, without loss of generality, that f ( a) > 0 and f ( b) < 0. Then by the intermediate value theorem, there must be a root on the open interval ( a, b). WebFor a given function f(x),the Bisection Method algorithm works as follows:. two values a and b are chosen for which f(a) > 0 and f(b) < 0 (or the other way around); interval …
